<p>PURPOSE: To manage/grasp the use frequency of an electronic pen input part by calculating the writing distance of the electronic pen and storing it into a memory. CONSTITUTION: This data processor is provided with the electronic pen 50, a digitizer 52 detecting the position of the electronic pen 50 and switch information and RAM 3 is provided with a writing distance calculation part 20 calculating the writing distance of the electronic pen 50. When an integration part 21 is started, the writing distance of the electronic pen 5 and the number of switching times are integrated on RAM 3 and they are compared with a prescribed threshold which is set in a prescribed register in CPU 1 by a comparation part 22. When the integrated writing distance and the number of switching times exceed the prescribed threshold, they are displayed on LCD51 and an operator is notified of that the use limit of the electronic pen 50 is going to run out. Thus, a manager can learn the operation situation of the electronic pen input part.</p> |
